Overview
Catherine has been part of the diabetes research team, led by Prof Andrew Hattersley since 2010, working on clinical research projects in diabetes, including genetics of diabetes and most recently stratification of Type 2.
She is currently manages the TriMaster clinical trial, a randomised double-blind three-way crossover trial of third-line diabetes therapies which aims to improve diabetes care by identifying groups of patients who may respond better to certain diabetes treatments. She is also involved in the NIHR Global Health project working to improve diabetes diagnosis and treatment in sub-Saharan Africa in collaboration with partners in Uganda and Cameroon.
Alongside these role she is a part-time PGR student looking at stratified medicine and treatment hetergeneity in Type 2 Diabetes.
Catherine is based in the NIHR Exeter Clinical Research Facility and UEMS Medical School. Previous studies include the MASTERMIND and RetroMASTER clinical studies, work with the Stroke Research Network for the INTERSTROKE study and the EU IMI-DIRECT and FP7-CEED3 projects.

TriMaster: randomised double-blind crossover study of a DPP4 inhibitor, SGLT2 inhibitor and thiazolidinedione as second-line or third-line therapy in patients with type 2 diabetes who have suboptimal glycaemic control on metformin treatment with or without a sulfonylurea—a MASTERMIND study protocol.

Abstract:
TriMaster: randomised double-blind crossover study of a DPP4 inhibitor, SGLT2 inhibitor and thiazolidinedione as second-line or third-line therapy in patients with type 2 diabetes who have suboptimal glycaemic control on metformin treatment with or without a sulfonylurea—a MASTERMIND study protocol
IntroductionPharmaceutical treatment options for patients with type 2 diabetes mellitus (T2DM) have increased to include multiple classes of oral glucose-lowering agents but without accompanying guidance on which of these may most benefit individual patients. Clinicians lack information for treatment intensification after first-line metformin therapy. Stratifying patients by simple clinical characteristics may improve care by targeting treatment options to those in whom they are most effective. This academically designed and run three-way crossover trial aims to test a stratification approach using three standard oral glucose-lowering agents.Methods and analysisTriMaster is a randomised, double-blind, crossover trial taking place at up to 25 clinical sites across England, Scotland and Wales. 520 patients with T2DM treated with either metformin alone, or metformin and a sulfonylurea who have glycated haemoglobin (HbA1c) >58 mmol/mol will be randomised to receive 16 weeks each of a dipeptidyl peptidase‐4 inhibitor, sodium-glucose co-transporter-2 inhibitor and thiazolidinedione in random order. Participants will be assessed at the end of each treatment period, providing clinical and biochemical data, and their experience of side effects. Participant preference will be assessed on completion of all three treatments. The primary endpoint is HbA1c after 4 months of therapy (allowing a range of 12–18 weeks for analysis). Secondary endpoints include participant-reported preference between the three treatments, tolerability and prevalence of side effects.Ethical approvalThis study was approved by National Health Service Health Research Authority Research Ethics Committee South Central—Oxford A, study 16/SC/0147. Written informed consent will be obtained from all participants. Results will be submitted to a peer-reviewed journal and presented at relevant scientific meetings. A lay summary of results will be made available to all participants.Trial registration numbers12039221; 2015-002790-38 and NCT02653209.
